• Characterization of the pore structure of materials. Estimation of the geometrical and topological properties of meso- and macro-porous materials (e.g. soils, rocks, tight reservoirs, adsorbents, catalyst supports) by combining percolation models with datasets from experimental techniques (e.g. Hg porosimetry, N₂ sorption) and calculation of relevant transport properties (permeability, electrical conductivity, effective diffusivity).
• Environmental impacts of carbon dioxide storage. Effects of CO₂ leakages from deep storage sites on shallow freshwater aquifers: experimental study and numerical modeling of the dynamic physico-chemical interactions of soil/groundwater/CO₂ (e.g. CO₂ dissolution, immobilized heavy metal release).
• Soil & groundwater contamination. Experimental study of the fate of persistent organic pollutants (e.g. per- and polyfluoroalkyl substances -PFAS) in the subsurface through visualization tests on glass-etched pore networks, and soil column tests. Numerical simulation of multiphase transport/reactive processes (advection, dispersion, dissolution, biodegradation, reactions) occurring during pollutant spreading /remediation in unsaturated and saturated zones.
• Treatment of soils and wastewater with advanced oxidation processes (AOPs). Design, development and testing of lab-scale and pilot-scale setups for the remediation of contaminated soils and wastewater with advanced oxidation processes (e.g. photocatalysis, ozonation, non-thermal plasma). Numerical modeling of flow, transport, and reactive processes to predict the performance of prototypes.
• In situ groundwater remediation by nanoparticles. Synthesis of stable zero valent iron nano-colloids from plant extracts (e.g. tea leaves, pomegranate). Quantification of the capacity of nanoparticles to remove organic (chlorinated hydrocarbons) and inorganic (Cr^VI) as bulk phase, dissolved in water and adsorbed on porous media. Development of true-to-the mechanism multi-scale numerical models.
• Enhanced oil recovery. Optimization of the interfacial/wetting properties of polymer-coated nanoparticles (PNPs) toward the mobilization of trapped oil ganglia from porous media. Preparation and characterization of PNP-based Pickering emulsions, and foams, and testing them as chemical flooding agents in porous media models (glass-etched pore networks & sandpacks) and core plugs. Correlation of the oil recovery efficiency with PNP properties.
• Biomass valorization. Development of cost-effective adsorbents with chemical activation and thermal treatment of agricultural wastes. Advances toward the development of low cost hybrid adsorbents capable to remove “cocktails” of multi-species pollutants (e.g. dyes, heavy metals, nitrates, PFAS) from wastewater.
